Types

type SFilePV 

type SFilePV struct {
	Key           SFilePVKey
	LastSignState SFilePVLastSignState
}

SFilePV implements PrivValidator using data persisted to disk to prevent double signing. NOTE: the directories containing pv.Key.filePath and pv.LastSignState.filePath must already exist. It includes the LastSignature and LastSignBytes so we don't lose the signature if the process crashes after signing but before the resulting consensus message is processed.

func GenSFilePV 

func GenSFilePV(keyFilePath, stateFilePath string) *SFilePV

GenSFilePV generates a new validator with randomly generated private key and sets the filePaths, but does not call Save().

func LoadOrGenSFilePV 

func LoadOrGenSFilePV(keyFilePath, stateFilePath string, s []byte) *SFilePV

LoadOrGenSFilePV loads a SFilePV from the given filePaths or else generates a new one and saves it to the filePaths.

func LoadSFilePV 

func LoadSFilePV(keyFilePath, stateFilePath string, s []byte) *SFilePV

LoadSFilePV loads a SFilePV from the filePaths. The SFilePV handles double signing prevention by persisting data to the stateFilePath. If either file path does not exist, the program will exit.

func LoadSFilePVEmptyState 

func LoadSFilePVEmptyState(keyFilePath, stateFilePath string, s []byte) *SFilePV

LoadSFilePVEmptyState loads a SFilePV from the given keyFilePath, with an empty LastSignState. If the keyFilePath does not exist, the program will exit.

func NewSFilePV 

func NewSFilePV(privKey crypto.PrivKey, keyFilePath, stateFilePath string) *SFilePV

NewSFilePV generates a new validator from the given key and paths.

func (*SFilePV) GetAddress 

func (pv *SFilePV) GetAddress() types.Address

GetAddress returns the address of the validator. Implements PrivValidator.

func (*SFilePV) GetPubKey 

func (pv *SFilePV) GetPubKey() (crypto.PubKey, error)

GetPubKey returns the public key of the validator. Implements PrivValidator.

func (*SFilePV) ResetWith 

func (pv *SFilePV) ResetWith(s []byte)

func (*SFilePV) SaveWith 

func (pv *SFilePV) SaveWith(s []byte)

func (*SFilePV) SignProposal 

func (pv *SFilePV) SignProposal(chainID string, proposal *tmproto.Proposal) error

SignProposal signs a canonical representation of the proposal, along with the chainID. Implements PrivValidator.

func (*SFilePV) SignVote 

func (pv *SFilePV) SignVote(chainID string, vote *tmproto.Vote) error

SignVote signs a canonical representation of the vote, along with the chainID. Implements PrivValidator.

func (*SFilePV) String 

func (pv *SFilePV) String() string

String returns a string representation of the SFilePV.

type SFilePVKey 

type SFilePVKey struct {
	Address types.Address  `json:"address"`
	PubKey  crypto.PubKey  `json:"pub_key"`
	PrivKey crypto.PrivKey `json:"priv_key"`
	// contains filtered or unexported fields
}

SFilePVKey stores the immutable part of PrivValidator.

func (SFilePVKey) SaveWith 

func (pvKey SFilePVKey) SaveWith(s []byte)

Save persists the SFilePVKey to its filePath.

type SFilePVLastSignState 

type SFilePVLastSignState struct {
	Height    int64           `json:"height"`
	Round     int32           `json:"round"`
	Step      int8            `json:"step"`
	Signature []byte          `json:"signature,omitempty"`
	SignBytes abytes.HexBytes `json:"signbytes,omitempty"`
	// contains filtered or unexported fields
}

SFilePVLastSignState stores the mutable part of PrivValidator.

func (*SFilePVLastSignState) CheckHRS 

func (lss *SFilePVLastSignState) CheckHRS(height int64, round int32, step int8) (bool, error)

CheckHRS checks the given height, round, step (HRS) against that of the SFilePVLastSignState. It returns an error if the arguments constitute a regression, or if they match but the SignBytes are empty. The returned boolean indicates whether the last Signature should be reused - it returns true if the HRS matches the arguments and the SignBytes are not empty (indicating we have already signed for this HRS, and can reuse the existing signature). It panics if the HRS matches the arguments, there's a SignBytes, but no Signature.

func (*SFilePVLastSignState) Save 

func (lss *SFilePVLastSignState) Save()

Save persists the FilePvLastSignState to its filePath.

type WalletKey 

type WalletKey struct {
	Version          int               `json:"version"`
	Address          types.Address     `json:"address"`
	Algo             string            `json:"algo"`
	CipherTextParams *cipherTextParams `json:"cp"`
	DKParams         *dkParams         `json:"dkp"`
	// contains filtered or unexported fields
}
